Since they didn't intend to risk their lives getting exploited by the Second Progenitor and they didn't want to follow the Blood Ancestor, they didn't have a place in the Evernight Territory.
At the same time, they were too weak to resist the Blood Ancestor. Thus, the only answer was to take refuge in the territory of a Great Devil with power that could rival the Blood Ancestor.
The Sixth Progenitor and Eleventh Progenitor immediately knew what they had to do. They intended to follow the Thirteenth Progenitor to Hecate's territory.
It was a good thing that they had sought out the Thirteenth Progenitor.
"I want to follow you, Old Thirteenth."
"Same here. Take me with you."
After hearing the two female Vampire Lords wanted to accompany her, Marianne immediately felt relieved.
